syngo.CT View&GO is intended for basic visualization of medical images that are used for diagnostic purposes. The software package is designed to support trained technicians and trained physicians in basic qualitative and basic quantitative measurements as well as in the analysis of clinical data that has been acquired and reconstructed on Computed Tomography scanners. The software package shall also provide the possibility to save image data and to trigger the transfer of image data to other systems, such as printers or archiving systems. The software package shall provide an interface to integrate additional advanced visualization and measurement tools.

Basic visualization of medical images includes, for example:

• Adjusting of windowing level presets

• Zooming and panning of images

• Multiplanar reconstruction (MPR) display

• Maximum intensity projection (MIP) display

• Volume rendering techniques (VRT) display

Basic qualitative and basic quantitative measurements include, for example:

• Distance measurements

• Region of interest (ROI) measurements

• Pixel lens to measure local HU values

Indications for use as stated in the FDA summary.
